The short dot I use, the VisionKing 1.25-5x has been an absolute champ. My biggest thing on it, especially with the use of larger profile goggles, is its eye relief. Short dots, compared to most other magnified optics, tend to have a lot longer eye relief. Running one on my AK, I would almost say it is too far back to use comfortably. But on any other platform with longer monolithic upper rail, is perfect.
The magnification is just right. I personally use about 3x for typical shooting/engagements or the full 5x if trying to ID targets. And also, it can be used pretty darn close to a quick acquisition red dot at the 1.25x.
Overall, I'm in love with them and will probably be picking up more to have on other guns soon.
